My WAR calculation is a combination of Baseball-reference and Clay Davenport; I believe it to be the "best" WAR number available for historical comparison. 8 WAR is an MVP quality season. The record is pythagorean adjusted for 162 games.

-And then came the 70s. I was born near the end of this season, if you'd like to blame me, you can. This is the first San Francisco team to have only a .500 pythag. King's fired early in the season, replaced by Charlie Fox, a Giant lifer, player, scout, minor league manager. Fox is the fifth manager (not counting Sheehan, since he didn't start a season) in fewer than 15 San Francisco seasons. Mays gets his 3,000th hit, Marichal his 200th win. In Mays's age 39 season, he was just shy of a 5 WAR player. Davenport's last year. McCormick's last year. Linzy's last year.
